All you have to do is have Jumbo Cactuar out and able to attack, Jarad out, and three mana open during the attack step
Narcolepsy can put a creature to sleep permanently, or if that's not good enough, get the entire opposing army dozing with Sleep
Just a couple words of warning
If the player or their opponent make an easily fixable mistake an incorrect land play or a spell cast out of sequence they shouldn't panic or get frustrated
Importantly, these are not the lands themselves, and they shouldnt be included in your deck as part of your land counts, unlike the Modern Horizons 3 land cyclers, which cost one mana to cycle
If your deck meets the constraint, you may choose up to one copy of that card as your companion
